Determination of Total Chlorine,Organic Chloride and Inorganic Chloride Content in Crude Oil by Furnace and Ion Chromatograph

A method for the determination of total chlorine in crude oil using a furnace and an ion chromatograph has been established. An atmospheric distillation method was used to obtain the fraction before 204 ℃( ASTM D86). The total chlorine content in the fraction was also determined by the furnace and ion chromatography. According to the result and the percentage of fraction in crude oil the organic chloride content can be calculated,and the inorganic chloride content in crude oil can be obtained by subtraction.
